TTF species intercalated in van der Waals gaps of MnPS3 single crystals were found to be in the state of mixed-valence, and their degree of ionicity was estimated at 0.8 from the Raman band observed at 1432 cm-1. The frequency difference between the Raman band and the IR band of the same origin, of which IR intensity was enhanced through the vibronic intensity borrowing from the charge-transfer transitions, amounts to 120 cm-1. This amount of frequency difference suggests that the intermolecular interaction between TTF species confined in MnPS3 is stronger than that in TTF radical-salt crystals.
